When Northridge (Tuscaloosa) running back Bo Scarbrough didn't get up after a first-quarter carry Friday night all of us at Hillcrest High School held our breaths hoping that the talented sophomore had just tweaked an ankle or had the breath knocked out of him. Unfortunately what we all feared was confirmed on Saturday when an MRI revealed the 6-foot-2, 215-pounder had torn his left ACL on a second-series rushing attempt.
